I've mentioned this before, but I like to stick on subjects like some kind of tumor.
I don't think government is important, and it gets progressively less important as the population under its purview increases. I know it is important, but not in the way people think. Government is important in the sense that it is the framework in which society functions. Government is not the society itself, but merely a section of the society with controlling functionality. I take the idea that government exists for the people to the extreme by saying that the actual existence of government is almost inconsequential since most of what people would and would not do they would be done in the absence of government.
For example, how often does the average person interact with the Federal government aside from paying income tax? They don't. Maybe join the army, or something, but little else. Our interactions with government increase as you go further down the hierarchy. Eventually, people start interacting frequently, but it becomes more of a group effort to solve problems than a classic idea of government.
It's not the most well-formulated idea, but I can back it up with an argument of absence. What is absent? An efficient, honest government. All governments, everywhere, are corrupt. Obviously, the degree of corruption is unknown, but it's obviously there because every now and then, we lift up the rock a little and are forever surprised at the nasty stuff we find. You'd think we'd get used to it.
But the world is getting better. More people have more money and food, technology is advancing, the environment is better (When's the last time you heard of a river catching on fire?) people are more equal, and we have more channels than ever(!). How is this possible if government sucks? Government is unimportant, that's how. It exists to keep people who feel important entertained. That's why government's subject matter never changes. They argue about the exact same stuff year after year, generation after generation. Government never actually gets anything done.
I know I'm using an odd definition of government, perhaps a better term would be politics, I'm not sure. Government is important, to be sure. The system is needed, but I think the system springs naturally from human nature. It sort of codifies that rule set needed from things like economy to work, but people treat it as much more than that. It becomes ideological, and financial, and all about change and straight talk. It all leads to absolutely nothing, but people harp on about it nonetheless until they die.
